GEORGE G SCHROEDER, OF WASHINGTON, DISTRICT OF COLUMBIA. COMBlNEDMECHANICAL AND ELECTRlC MOTIVE POWER FOR TRAINS.

Specification of Letters Patent.

Patented Sept. 18, 1906.

Application filed April 17, 1905. Serial No. 266,102.

Be it known that I, GEORGE G. SonnoE- I DER, a citizen of the UnitedStates, residing at Washington, in the District of Columbia, haveinvented new and useful Improvements in a Combined Mechanical andElectric Motive Power for Trains, of which the following is aspecification.

This invention has relation to combined mechanical and electric motivepower for trains; and it consists in thenovel construction andarrangement of its parts, as hereinafter shown and described.

The object of the invention is to provide a car or a train with anengine which is geared to and adapted to operate the axles of one set oftrucks.

A rotary generator is so located with relation to said engine as to beoperated thereby and is electrically connected with suitable storagebatteries carried by the car or cars. The remaining trucks of the car orcars, ex cept the one carrying the axles, heretofore referred to, whichare geared to the engine, are provided with electric motors, which areelectricall connectedto the saidstorage batteries and also to theaforesaid generator. Thus the axles of the remaining trucks may beelectrically operated, and by providing such a combination all'of thewheels throughout the train may be converted into drivers. The currentgenerated by the rotary generator may also be used for lighting andsignaling. By providing such a combination the engine alone may be usedunder ordinary circumstances for propelling the car or train, and underextraordinary conditions both the engine and the electric current may beused for propelling. Furthermore, the trailing cars are provided withstorage batteries which may be charged, and when the said trailers arecut loose from the train the current thus stored may be used for movingthe said trailers and also for maintaining the lights.

With these and other objects in view my invention consists in theconstruction and cornbinationhereinaft-er described, and pointed out inthe appended claims.

In the accompanying drawings, Figure 1 is a side elevation of atrain-provided with the herein-described means for propelling the same.Fig. 2 is a side elevation, partly in section, of the forward car of thetrain. Fig. 3 is a longitudinal-sectional view of the front end of theforward car. Fig. 4 is a horizontal sectional view of the front end ofthe forward car. Fig. 5 is a top plan view of the runninggear of atrailer. Fig. 6 is a top plan view of a truck used on the forward carand also on the trailers, said truck being provided with an electricmotor geared to the axles. Fig. '7 is a side elevation, partly insection, of the truck as shown in Fig. 6 and Fig. 8 is a diagram maticview of the electric circuits used in a forward car and trailer.

The forward car 1 is provided at its front end with a compartment 2,within which is located an engine 3. Said engine is preferably of therotary hydrocarbon type. The oil-tank 4 is located just below the roofof the car and is connected, by means of the pipe 5, .with thecarburetor The pipe 7 connects the carbureter 6 with the mi or 8', andthe pipe J connects the mixer S with the eng' 'ie 3. The oil tank,carburetor, and above referred to are of the ordinary construction. Theoil is deposited in the said tank, from which place it passes through.the pipe 5 into the eurbureter (5, where it is converted into gas. Thegas then passes through the pipe 7 into the mixer S, v. e it is mixedwith the air. The n'iixture thus produced then passes to the cylindersof the engine 3 through the pipe 9. Aside from the fact thatthe type ofthe engine 3 is of the ro struction of the said engine forms no part 1;"the invention.

In the drawings the engine 3 is shown as located on the forwardplatform, and adjacent thereto is located a rotary generator 10. Theshaft of the said generator 10 is in alinement with the shaft of the enine 3. A gearing is provided between the shaft of the engine 3 and theshaft of the generator 10. Said gearing consistsv of an intermediateshaft 11, which is alined with the shafts of the engine 3 and thegenerator 10. A set of friction-disks 12 is provided at the point wherethe shaft of the tary hydrocarbon type the particular con- 7 engine 3meets the end of the shaft 11, and a set of friction-disks 13 isprovided at the point where the end of the shaft of the generator 1Umeets the end of the intermediate shaft 11. The lever 14 is adapted tooperate the sliding member of the set of friction-disks 12, and thelever 15 is adapted to o )erate the sliding member of thefriction-dis s13. A beveled gear-wheel 16 is located upon the intermediate shaft 11.The vertical shaft 17 extends through the bottom of the body of mesheswith a slmilar gear-wheel (not shown) 1 tached to the other end of thesaid bell-crank.

the car The beveled gear-wheel 18 is fixed to the upper end of the shaft17, and the'said beveled gear-wheel l8 meshes with the beveledgear-wheel 16. The beveled gear-wheel 19 is fixed to the lower end ofthe vertical shaft 17. The horizontal shaft 20 is journaled under thebottom of the body of the car. Said'shaft is provided at its forward endwith a beveled gear-Wheel 2 1, which '23, and the said sleeve 25 may beso moved as to take both of the gear-wheels 26 and 27 out of mesh withthe said beveled gear-wheel 23. The means for moving the sleeve 25 andits attachments consists of a bell-crank lever 28, suitably fulcrumedand which engages at one end the said sleeve 25. The rod 29 is atlever28 and connects with the lever 30, lo-

cated in the compartment 2.

The beveled gear-wheel 31 is fixed to the lower end of the verticalshaft24. The shaft 32 is journaled to the truck of the car and is providedwith the beveled gear-wheel 33,

which meshes with the beveled gear-wheel 31. At one end the said shaft32 is provided with the beveled gear-wheel 34, which meshes with abeveled gear-wheel 35, fixed to the forward axle of the truck. Therearend of the shaft 32 is provided with a gear-wheel 36, which at theforward end ,of the shaft 37., The rear end of the shaft 37 is providedwith a beveled gear-wheel 38, which meshes with a beveled gear-wheel 39of the rear axle of the truck.

It will be observed that the bracket 22 and the contents thereof arecentered in vertical 'alinement with the pivotal point 40 of thecartruck, and therefore as the body of the car projects out of alinementwith the truck in rounding a curve the location of the bracket 22 and1ts .contents at the particular point sipecified compensates for andpermits such fierence in direction between the car-body and the truck. p

When the members of the friction-disks 12 are in engagement, rotarymotion is trans- I .mitted from the shaft of the engine 3 to theintermediate shaft 11, which rotates the beveled ear-wheel 16. This inturn rotates the be've ed gear-wheel 18 and the shaft 17. The wheel 19,carried by the shaft 17 and which engages the wheel 21, carried by theshaft 20, rotates the last said shaft. By the manipulation of the lever30 the sleeve 25 and its atgear-wheel 26 or the gear-wheel 27into meshwith the gear-wheel 23. The bri ngm' into such mesh of the gear-wheel 26caus s the shaft 24 and its attachments to rotate in one direction andalso the axles of the truck to rotate in one direction. The bringinginto such mesh of the gear-wheel 27 causes the said shaft 24 an'd'itsattachments to rotate in the opposite direction. Thus the car or trainmay be controlled in its forward or backward movement by the operationof the lever 30. Also the said lever may be so moved as to bring boththegear-wheels 26 and 27 out of mesh with the gear-wheel 23, in which casethe rotary motion to the parts below the said bracket 22 is interruptedand the car comes toastop. v

The rear truck of the. forward car iszprovided with a motor 41. Saidmotor is centrally'located u on the said truck, One end of the shaft ofthe said motor 41 is connected by a chain of gear-wheels 42 with thefront axle of the truck and the other 'end of the shaft of the saidmotor is connected by a chain of gear-wheels 43 with the rear :axle ofthe truck. a 4

, The current-wires 44 44 connect with the said motor 41 and areadaptedto transmit the electric current to the same. Each car isprovided with a set of storage-cells 45, which are electricallyconnected to the electric motor or motors of the res ecti've car,carrying the said storage-cell. he said storage-cells are alsoelectrically connected with the enerator 10, located upon the forwardcare the train.-

Fig. 8 of the drawings shows a diagrammatic view of the variouscircuits. The wire a 44 connects at one end one of the brushes of thegenerator 10. The other end (if-the said wire connects one of thebrushes of the motor 41. If two or more cars are used upon the connectedwith the electric wires of the next adjacent car by means of plugs inthe wellknown' manner. Therefore a description of the circuit of one-carwill answer for the descri tion ofall.

e wire 46 connects the opposite brush of the generator 10 and'is rovidedwith the branches 47 and 48, each 0 which is provided with a switch. Thewire 49 leads from a point opposite the switch of the wire 48 to thebattery 45, while the wire 50 leads from a point opposite the switch ofthe wire 47 to the battery 45 of the next car.

The wire 51,

same train, the electric wires of one 'car are I TO having a switch,connects thewire 44 withthe 1 battery of the next car, this arrangementbeing necessary to sup ly power to the motors 41 when the storageatteries 45 are employed in lieu of the generator 10. The wire 52connects the wire 51 with the battery of the forward car and also withthe motor 41 of the forward 'car, also with the lights 53. The

or upon any individual car when it is cut loose wire 52 is provided witha switch 54, and the l other end of the said wire 52 connects with theWire 49.

If for any reason the engine 3 should become disabled, so as to preventthe operation of the generator 10, the circuit is closed through Wire51, thus connecting the storage batteries 45 with the motors 41 throughwire 44. Wires 49 and 50 of course become dead when the generator 10ceases to operate. As soon as the circuit is closed between the storagebatteries and the motors the latter are rotated under the influence ofthe current from said batteries, and rotation is imparted to the axlesthrough the gears 42 43. (See Fig. 5

The system for wiring forms no essential part of the invention, as anyother system which accomplishes the same as that shown and described maybe employed. The object of the electric system as described. is to)rovide a means for storing current 111 the batteries. The said currentwhen so stored may be used for lighting and as a means for operating theelectric motors.

The operation of the electric motors may be accomplished while the trainis in its entirety from the train.
